  • Paper conditioner with articulating back-up/transfer rollers
    Patent number: 5937258
    Abstract: A paper conditioner to control image dependent curl which uses one or more counter-rotating transfer rollers which are initially spaced from their respective back-up rollers in the intercopy gap, and which come together as the lead edge enters the nip area, and separates when the trail edge is about to pass. This permits the rollers to have a less demanding runout tolerance by bringing the rollers together when the sheet is in the nip, and then articulating the rollers apart in the intercopy gap.
